In the temperature range of 90 to 100 °C a first endothermic effect could be observed. A second endothermic effect was detected in the temperature range of 320 to 390 °C. No further thermic effects could be observed up to the maximum temperature of 500 °C.

Results of the DSC-measurements

No.	Sample weight / mg	Onset of Effect / °C	Range of effect / °C	Weight loss / mg	Atmospheric pressure / hPa
PN19667	10.05	92.70 354.82	90 – 100 (endo) 320 – 390 (endo)	10.05	991.9
PN19668	10.23	92.90 350.52	90 – 100 (endo) 320 – 390 (endo)	10.23	991.9

 

During the heating phase a distinct endothermic effect was observed in the temperature range of 90 – 100 °C, which can be assigned to the melting of the test item.

As the onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 92.80 °C, this temperature can be used as melting point. The test item has a melting point of 92.8 °C.

Conclusions:

The melting point was determined to be 92.8 °C.

Executive summary:

The melting point of the test item was determined by Differential Scanning Calorimetry according to Regulation (EC) No 440/2008 Method A.1. and OECD Test Guideline 102 (1995). In the DSC measurement the first endothermic effect could be observed in the temperature range of 90 – 100 °C, which was followed by second endothermic effect in the temperature range of 320 – 390 °C. The first endothermic effect is assigned to the melting point. As the onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 92.80 °C, this temperature can be used as melting point. The test item has a melting point of 92.8 °C.

Additional information

The melting point of the test item was determined by Differential Scanning Calorimetry according to Regulation (EC) No 440/2008 Method A.1. and OECD Test Guideline 102 (1995). In the DSC measurement the first endothermic effect could be observed in the temperature range of 90 – 100 °C, which was followed by second endothermic effect in the temperature range of 320 – 390 °C. The first endothermic effect is assigned to the melting point. As the onset temperatures in both tests do not deviate by more than 0.5 K from their mean value of 92.80 °C, this temperature can be used as melting point. The test item has a melting point of 92.8 °C.

As supporting information the melting point was described as 91.5 °C in a reliable data collection (reference 4.2-1).
